It is longtime it is such, and I do not think it could take long to fix it.

When you finish a game and you want review it, the first move button "|<" does NOT work.

Instead, the previous move button "<" takes to the beginning.

This happens ONLY the first time you press those buttons.

Second - if you click a move in the list of moves to go in the middle of game, if you afterwards click next or previous move buttons, the game jums to the position they were last used and NOT that you are VIEWING.

well that is not a problem because mine is working fine..and i can review my games after ends or via game history the simple process as you know if you wants to review your game..then first of click ">" play/pause tab after that you can try ">" & "<"these buttons or try to change your browser...Firefox,IE is good for chesscube..Chrome have some problem now in these days...
